Description
Technical field
The present invention relates to a kind of ceramic bearing rolling element, be specifically related to a kind of to there is ceramic bearing rolling element of the characteristics such as limit speed is high, high temperature resistant, cold-resistant, wear-resisting, corrosion-resistant, diamagnetic electrical insulation and preparation method thereof, belong to ceramic technology field.
Background technique
Bearing (" Bearing ", Japan's person " axle is subject to ") is in mechanical transmission course, play parts that are fixing and reduction load friction factor.Alternatively, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor in power transmission process and retainer shaft central position.Bearing is a kind of very important component in contemporary machinery.Its major function is supported mechanical solid of rotation, in order to reduce the mechanical load friction factor of equipment in transmission process.By the difference of motor element frictional property, bearing can be divided into rolling bearing and sliding bearing two class.
China is one of country of comparatively early invention rolling bearing in the world, and in Chinese Ancient Books, the structure about axle bearing is early on the books.From archaeology historical relic and data, the bearing with modern rolling bearing structure blank that China is the most ancient, comes across the Yongji County Xue Jiaya village of modern Shanxi Province of B.C. 221 ~ 207 years (Qin Dynasty).After founding of New, particularly since the seventies in last century, under the powerful promotion of reform and opening-up, bearing industry enters a brand-new high-quality fast-developing period.
At 17th century end, C. watt of Lip river of Britain manufactures and designs ball bearing, and to be contained on postal car P. that is on probation and Britain and to irrigate the patent that think of obtains ball bearing.18 the end of the century Germany H.R. hertz deliver paper about ball bearing contact stress.On the basis of hertz achievement, the R. of Germany executes Trebek, the people such as A. handkerchief nurse Glenn of Sweden has carried out a large amount of tests, contributes to the design theory of development rolling bearing and Calculation of Fatigue Life.Subsequently, the N.P. Dinko Petrov application newton law of viscosity calculation bearing friction of Russia.
Bearing is the important foundation component of all kinds of mechanized equipment, and its precision, performance, life and reliability play conclusive effect to the precision of main frame, performance, life and reliability.In engineering goods, bearing belongs to high-precision product, not only need the comprehensive support of the subjects such as mathematics, physics theory, and need materials science, heat treatment technology, precision machining and surveying, Numeric Control Technology and the effective subjects such as numerical method and powerful computer technology to serve for it, therefore bearing is again a product representing national science and technology strength.
At present, the applied environment such as long lifetime, high stability, the high rotating speed of textile machinery, the corrosion resistance of Chinese workers' industry of automotive industry requires exploitation a kind of high speed, heavy duty, heatproof, lubricates long-life bearing less, technology content is very high, be the perfect adaptation of new material, new process, new structure, it is very significant for therefore developing a kind of ceramic bearing rolling element.
